Thank you all for the feedback. It is a 1/4 x 20 thread right?

 

I've been using a 1/4-20 cap head screw with hex inset on my Zeppelin seat. I tighten with a long ball-tip allen wrench. But you still have to get the screw in there upright so you can tighten without cross-threading. I'm looking for that thumb screw.

 

Why don't you guys simply used a double threaded 1/4 x 20 extender. Put the thumb screw on one end and then thread a long piece of 1/4 x 20 all thread using red locktite or even locking it in with a nut and lockwasher on the other end.

 

Why use something like all thread that eats up everything that gets next to it ??????
You do have a point about having threads at both ends tho. So cut the head off a bolt & thread the top to screw on a **** with red, or green loctite. If you do use all thread, put a cover of a rubber or plastic tube to protect everything from the threads.
Also you can also slightly point the threaded end as to find the threaded hole easily, and shorten the threads if you want to screw the bolt less.............
Always keep it simple !

 

This is my fix for the seat screw. I used a double nut on the bolt. All parts purchased at Ace Hardware.

 

That will work fine, but if anything gets against those threads, it will eat it like a file. Like your seat when someone is setting on it ?
The addition I would make to it is a piece of rubber tubing like surgical or any thin rubber tubing just to be safe.
I have the Road Zeppelin seat, & the pad goes back farther. Maybe yours won't reach it. How about the back lower pad?
Just my opinion........

 

Writeman, looks good but add the clear vinyl tubing as suggested to be on safe side.

 

I'm not sure how important the seat retaining screw is. I discovered last night mine's gone MIA. And, I had not noticed until then. My seat fits pretty snug and does not move around. I may not replace the screw and am thinking of fitting a short stud the rear seat mount fits onto.

Not related to this specific problem, but I'll tell a little seat related story on my self.

I bought my '11 Tri-G from the original owner. It has a driver back rest. I figured out that the screw in the back would release the seat, but did not know how I was going to get the seat over the backrest pad, so I took that off the backrest post so I could slide the seat over it. Once I had the seat off, I could see the release lever to pull the whole assembly off, DUH!!. I could also see the cable that led over to the lever that lets you adjust the angle of the backrest, which I did not know I could do.

You live you learn.
